If the beautiful leaves on the maple turn yellow in the middle of the season, there is a need for horticultural action. What causes a sensation from September as a bright autumn color indicates a cultivation problem in spring and summer. You can read about the most common causes with tips for solving the problem here.
Maple will turn yellow prematurely if it lacks nutrients
This is why maple leaves turn yellow prematurely
Do not agonize over yellow discolored leaves, but carry out an analysis of the causes. The following overview summarizes the most common triggers for the problem with hints for the solution:
- Drought stress: water maple immediately and more frequently from now on
- Nutrient deficiency: fertilize at least once a year with 3 l of compost and 100 g of horn shavings (€32.93) per square meter
- Sunburn: transplant within the first 5 years, shade older maples in full midday sun
If a potted maple is suffering from yellowing leaves due to drought stress, run water on the root ball until it runs out of the bottom opening. Ideally, you can remedy a lack of nutrients in the bucket with a liquid fertilizer for green plants. Changing the location to a semi-shady place helps against sunburn.
